IGS President Elect
Sam R. Allen
Mr. Sam R. Allen is honored to be nominated by Dr. Jorge Zornberg, former IGs President, to be the next President of the IGS.
Mr. Allen is the Director of the TRI Environmental Group (TRI), a globally active, independent geosynthetic laboratory and research services provider. His work over the past 35 years has involved significant interaction with public and private entities around the world giving him a strong understanding of the needs in world regions for geosynthetics, infrastructure, and sustainability.
Mr. Allen volunteers time to numerous industry-growing organizations. He has served as the Executive Chair of ASTM Committee D35 on Geosynthetics and currently serves as the group’s Membership Secretary. He is the current WG 5 Convenor on Geosynthetic Durability on ISO Technical Committee 221 on Geosynthetics. And, he has served on the Board of Advisors for the Geosynthetic Institute (GSI) for 20+ years.
Importantly, Mr. Allen has been inspired by and dedicated himself to the IGS. He has been elected to the IGS Council (2006, 2010, co-opted 2014, elected 2018), chaired the Education Committee (2008 – 2010), co-chaired the Pan-American Activities Committee (2010), helped launch the Educate the Educators (EtE) program (Argentina – 2013, United States – 2015), and chaired the Communications Committee (2014 – present).
He has also led or contributed substantially to major communications endeavors, such as the Two for a Few series, expanding the IGS’s digital and social media presence, helping manage the rebuild of the IGS Digital Library and IGS website, and working on the Did You Know sustainability campaign.
Mr. Allen strongly believes that the IGS sits at the precipice of a new time of critically important messaging to permanently establish our materials and applications as absolutely necessary to sustainable development and environmental protection, while differentiating them from harmful single use and polluting plastics. Success will require education, awareness and trust from the users of our materials. These are all missions that Mr. Allen brings to his work with the IGS. He combines his scientific background with his passion for growing geosynthetics in engineering around the world.
Without question, Mr. Allen is ready to assume the very important leadership position of the IGS Presidency.
Mr Edoardo Zannoni is a Registered Professional Engineer and Chartered Engineer working for Knight Piesold Southern Africa (KPSA) as Section Manager: Geotechnical. KPSA is a worldwide consulting engineering firm with more than 100 years’ presence in Africa, providing engineering services to the public and private sectors. He has worked in the geosynthetic industry for more than ten years in technical roles, business management and project management, working in many African countries including South Africa, Ghana, Egypt, Mozambique and Tanzania.
Mr Zannoni served as President of the South African IGS Chapter (GIGSA) from 2014 to 2018. He is the current Chair of the South Africa Bureau of Standards (SABS) Committee in Geosynthetics TC 81E and member of ISO TC 221: Geosynthetics representing South Africa. He is also on the technical review panel for the South African Institute of Civil Engineers (SAICE) and regularly helps to deliver geotechnical modules in universities across South Africa. He was recognised with the IGS Young Member Service Award in 2014.
Mr Zannoni’s dedication to IGS globally began over ten years ago as a Council member, and Chair of the African Regional Committee, becoming part of the team that successfully delivered GeoAfrica 2013 in Ghana. He has taken part in numerous IGS ambassadors’ programmes in Mozambique, Morocco and Egypt, leading to the establishment of two new IGS Chapters. Mr Zannoni is the current IGS Secretary General and has contributed to initiatives such as the appointment of the Executive Director and new guidelines for the International Conference on Geosynthetics. As Chair of the Council’s Recognitions Task Force, he has driven the introduction of new IGS “named lectures”, which will further raise the international profile of IGS members’ contributions.
Mr Zannoni’s vision is for geosynthetics to become a pivotal technology in infrastructure- related industry as their resiliency compared to natural materials delivers more reliable environmental protection through sustainable solutions. The IGS can become the flywheel and the apex of this increasingly complex industry, consolidating many years of technological advancement and providing a solid framework rooted in technical know-how. As Vice President, Mr Zannoni would strive to ensure that geosynthetics are adopted worldwide; referenced by end-users, governments and engineering practitioners, all recognising the sustainability benefits they bring.
Newly Elected IGS Council Members
Mikio Kubo is honored to become a candidate for IGS council member with strong support of Japan Chapter of IGS. He will be the first practitioner representing Japan. He will contribute to the IGS effectively as a practitioner with vast experience of natural disasters and a wide knowledge of geosynthetics solutions relevant to such circumstances.
Kubo started his career at Teijin focusing on the development of polyester fibers for base clothes of industrial usages and flame retardant aramid fibers. He spent 18 years at Teijin and then left to form his company, Eternal Preserve, in 1996.
Eternal Preserve partnered with Linear Composites (UK) to introduce a high strength geogrid for embankments on soft ground constructed by Japan Highway Public Corporation. The design and construction methods were widely accepted and have become a preferred solution in the highway construction.
Since 2010 he has been responsible for organizing General Incorporated Association “Study group for deformation control by geosynthetics”.
As an IGS council member he would dedicate his time spreading awareness of the positive environmental impacts of the use of geosynthetics in infrastructures and their maintenance, whilst liaising efficiently between the IGS headquarter and chapters to maximize their relationships.
I solicit the support of IGS members to serve on the IGS Council. I am already contributing to IGS initiatives in two capacities: as the chairman of the Technical Committee on Hydraulics, and as the liaison to ICID. I have previously served on the council between 2010 and 2016.
On the regional level, I am Secretary of IGS-NA, on the Organizing Committee of the IGS-NA Conference in 2024, and on the IGS-NA bidding team for hosting the 13th International Conference on Geosynthetics in Montreal in 2026.
In addition to my IGS commitments, I also support the development of the Geosynthetics Industry through International Standardization. I am currently chairman of ASTM D35.10 on geomembranes, and chairman of the Canadian Mirror Committee of ISO TC221.
I am working as an independent expert based in Montreal, Quebec, Canada. I am supporting public agencies, designers and manufacturers with design, quality, long-term performance and durability of geosynthetics as well as polymeric materials used in buildings.
My most significant previous experience was to manage SAGEOS, a Geosynthetics Testing and Research Laboratory based near Montreal. Further details on myself, and a list of my publications can be found at www.ericblond.com or https://www.linkedin.com/in/geosynthetics-canada/.
